Like the OP I really like the mundane items. Wandering through a place with lots of dried up ink wells tell me something about the inhabitants. Glass chalices and wooden bowls tell me something about how the people were living. It's part of the art and the BG3 art is fantastic. They did a great job of making places look lived in -- from the monks who wrote all day to the depressing squalor of the hook horror hermit. The mundane items also make the real treasures seem like treasures. When I find silver platters in a goblin chest I think "must have been taken from one of the temple altars
And they have found way to make these mundane items meaningful in two different quests that I can think of -- one that requires that you were watching so see if these items seemed out of place. (okay fine
comes with HUGE hint but still)
The hag's hut is perhaps my favorite setting -- the transformation from a quaint cottage to a house of horrors is foreshadowed by that lovely toad shaped tea pot the kind old lady has in the grove. Quaint, mundane, curiosity piece or emblem of a sadist? Turns out to be latter -- the hag is just someone who would make tea pots out live toads. Perhaps they are alive still just paralyzed and held in suspended animation. Shivers. Suspicion.
I just don't have the inventory burdens other have I mentally filter them out the mundane items and they just don't show up in my inventory. I get why some do -- these are often used in crafting menus but if there is an item I fear might have a DOS like use like a crab claw, starfish or undies I can just "send to camp".
